Claims.

The invention relates to paper or fiber containers particularly designedas a single service container for holding milk or other liquids, and issusceptible also of holding granular or other 5 commodities of anon-fluid nature. The inven tion relates to the class of containersfully disclosed in my issued Patents No. 2,089,958, granted August 17,1937, and No. 2,085,979, granted July 6, 1937, for Containers. Thepresent invention has for its objects to.provide certain 'new and usefuladvantages over such a container to which my said patents aredirected.

A principal object of theinvention is to provide a paper or fibercontainer of the character described, the body. and one end wall ofwhich is of two-part construction, said parts being capable ofconvenient folding and telescoping together to comprise a completedtubular and preferably non-circular body including as a part thereof astrong end wall of double thickness.

A further object of the'invention is to provide a container of thecharacter described which may be constructed of web or sheet material ofmuch smaller dimensions than in the instance of the container bodycontemplated in my aforesaid issued patents. A feature of the instantinvention resides in the fact that the two-part container body isstrongly reenforced at its ends and at its side or corner edges, therebyrendering the same highly resistant to the shock and strains of use inthe packaging and dispensing of liquid contents, such as milk or thelike.

A still further object of the invention is to provide a paper or fibercontainer having a closure member hingedly secured to an end wallthereof, the features of construction being such as to permit said endclosure member to be se- I cured to the desired end wall adjacent thefilling and dispensing opening while one of the blanks of the two-partbodyvis in the flat and prior to folding and assembling, or said closuremember a may be attached to the container after the 'two- 7 .part bodyhas been assembled and adhesively or otherwise secured together, andprior to attaching thereto a separate and memberat the opposite open endof the receptacle.

When the closure member .is secured to an end wall of the partiallyassembled receptacle, the manner of securement provides an addedreenforcement to hold the end' wall of double thickness closely togetherthereby cooperating with the'usual adhesive in maintaining theconformation andrigidity of the completed package.

Numerous other objects and advantages of the invention will be apparentas it is better underreference to Figs. 1 to 8 inclusive, In indicatesgenerally one of the body blanks and II its comstood from the followingdescription, which, when.

taken in connection 'with the accompanying drawings, discloses a Ipreferred embodiment thereof.

In said drawings, 1 Fig. 1 is a plan view partiallybroken away of one ofthe fiber or paper blanks of which the container body is constructed,said view indicating in dotted lines the manner of folding the blank. V

Fig. 2 is'a similar view of the remaining blank which enters into theconstruction of the container body." I

Fig. 4' is a similar view showing the completed container with thebottom wall secured inp0s1- 20 tion and a. closure member'attached tothe opline. ii -6 showing the completed container in accordance 'withthe assembly of Fig. 7.

Fig. 9 is a plan view similar to Fig. 1, showing a. slightly modifiedconstruction of the corresponding body blank. I

Fig. 10 is a perspective view similar to, Figs. 3 and 7 and showing thetwo body blank members in partially assembled or telescoped relation.

Fig. 11 is a perspective view similarto Figs. 4 and 8, and showing thecompleted container assembled as indicated in Figs. 9 and 10.

Referring to the drawings, and withparticular panion body blank. Theblank member III is cut away as shown at. a to constitute opposite sidewall members 12, 13.. and an integral end or top wall portion l4.Afilling and dispensing opening indicated at 15 is provided in the'topwall member. The blank 19 is further scored or creased along foldinglines 16 to provide side wall enclosing flanges ll at the side edges ofthe body-wall members 12 and I3, respectively.

' Said opposite side wall portions I 2, I3, are formed by folding theflat blank along score or crease lines I3, defining the opposite edgesof the top wall. Depending opposite flange portions l9 are provided inthe top wall M by folding the blank along the oppositely disposed scorelines provided in the top wall, it being understood that the flangeportions l1 and I9 are folded so as to extend in the same direction orinwardly of the body blank to produce an integral'U-shaped wall portionbest seen in Fig. 7.

The companion body blank H is similar in material respects to the bodyblank it, the same being folded along spaced score or crease lines 2| toprovide oppositely disposed spaced side wall portions 22 and 23, and anintermediate top .o1-.--

end wall portion 24. A filling and dispensing opening indicated atisprovided in the top wall and is disposed to register with the opening{5 when the blanks are in the partially assembled position as shown inFig. 3.

In assembling the two-part bodyto form the l finished containerillustrated in Fig. 4, the blank members It and I l folded as described,are turned at right angles and the-body blank member H is inserted ortelescoped over the blank member II as shown in Fig. 3, ,with the flangeportions IT and I! of the inner blank member I'll engaging the oppositemargins of the opposite side wall members 22 and 2.3 of the outer foldedblankmember ll. Suitable adhesive, preferably a heat.

sealing thermo-plastic adhesive, is or may be provided on the outersurfaces of the flanged portionsll of the blank member land which servesto seal the engaged parts securely in position. The top end wall of theassembled container "body is of double thickness consisting of the wallportions I4 and 24 having the registering and filling apertures l5 and25 therein.

If desired, the assembly may be made by reversely telescoping the blanksas shown in Fig. 1 wherein thefiange portionsll of the blank member. III are disposed outwardly of the nonflanged innerblank member H insteadof inwardly thereof as shown in Figs. 3 and 4. In. such instance theinner surfaces of the inwardly turned flanged portions llv of the blankmember III are preferably provided with a suitable ther-r mo-plasticadhesive so as to secure said flange portions to the adjacent wallportions22 of the formed by the registering apertures I5, 25. Saidclosure element further includes an outwardly projecting finger engagingtab portion 29 to enable the plug to be released from the closure whendesired for the purpose of filling the contamer or for dispensing itscontents. The staple -2'| permitsthe closure member to be hingedupwardly and downwardly thereon for reclosing the container withoutdisplacement of the closure relative to the aperture, therebyconstituting the closure a permanent part of the cont-ainer body. Whenin closed position the inner wall portions of the cup shaped section 23may be expanded outwardly to engage beneath the top wall of thecontainer to serve as a mechanical lock insuring the outer telescopedmember as shown in Figs.

against inadvertent displacement of the closure relative to the fillingopening. a

.top wall 2% of the blank member ll while said members are in the flatand prior to folding, telescoping and assembling, depending upon whichbody blank member 10 or II constitutes 4 and 8 respectively. 1

After the U-shaped body blank members l0 and H are completely telescopedtogether, the bottom or open end of the container is subjected to diepressure to reenforce such end and secure a bottom closure memberthereto; Under such die action the lower side wall portions l2, I3; 22and 23 are inclined o r bent inwardly as at 30 (Fig. 6) and thenceoutwardly as at 3| to constitute a shoulder or ledge providing an abutsment for an imperforate end closure member 32 conforming to theconfiguration of the said end walls. After the closure member 32 isinserted in position the lower wall portions are bent inwardly thereoveras indicated at'33 to securely lock the same in position. A suitablethermoplastic adhesive is preferably provided at this area to securelyseal the end closure member 32 in place between the portions 3| and 33of the container body wall. In'this manner a secure reenforced endconstruction is provided for the two-part body wall oppositeto thesubstantially integral end portion having the filling and dispensingopening and closure element 26.

The completed container may be .rendered moisture and liquid proof, aswell as completely sterile, by coating the inner and outer walls thereofwith a suitable wax like material such as paramm-such coatingbeing-'preferablyprovided by passing the completed container through abath of melted parafin or the like while the closure element 26 is inopen position. Surplus paraffin is drained from the container as itleaves the. bath,.after which the closure member 26 is inserted in thefilling and dispensing opening and removably sealed in place by pressureand the adhesive qualities of the paraflin as the same becomes cooled orchilled after the container leaves the bath.

In the slightly modified embodiment of Figs.

9 to 11, inclusive, the body blank member II is similar tothe body blankIn of the hereinabove to closely register the end wall members 24, "a

and apertures 25, I511 with one another. After assembly the side flangeportions Ha of the as by heat sealing the previously appliedthermoplastic glue to the adjacent surfaces of the side wall portions 22of the inner blank H.

The open end of the assembled container is provided with an end closuremember similar to the closure member 32, and is subjected to the samedie pressing action, and the end 010- sure member is adhesively securedin place as in the instance of the heretofore described embodiment ofFigs. 1 to 8, inclusive. The closure member 26 is also secured in placeto the top wall of the container as in the instance of the firstmentioned embodiment, either by stapling the same to the blank member lladjacent the filling and closing opening while said blank is in theflat, or by stapling the same to both end wall portions 24 and Ma.- ofthe completely assembled blanks prior to inserting and securing thebottom end closure member 32 in position. The completed container as inthe instance or" the first mentioned embodiment may then be subjected toa melted paraflin or other suitable bath of wax-like material so as tocoat the inner and outer walls thereof and render the same moisture andliquid proof as well as completely sterile and in readiness for fillingand dispensing purposes.

In the event the contents are of solid or granular material theinvention contemplates if desired filling the container after thetwo-p'art body has been assembled and secured together and prior to theapplication of the end closure member thereto.

.The advantages and nature of the reenforced end of the container havingthe closure element 32 secured therewithin, are more fully pointed outin my prior patents hereinabove referred to.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.
